PHP - Call Php Functions Using Ajax
Hello guys
is it possible to create a single php file to contain all the functions to be called via AJAX and get AJAX to call the specific function required rather than having to create individual pages for each AJAX request you need to make? Many Thanks Similar TutorialsHello, I've been trying this for hours now, looking at different examples and trying to change them to work for me, but with no luck... This is what I am trying to do: I have a simple form with: - 1 input field, where I can enter a number - 1 Submit Button When I enter a number into the field and click submit, I want that number to be send to the php file that is in the ajax call, then the script will take that number and run a bunch of queries and then return a new number. I want that new number to be used to call the php script via ajax again, until no number is returned, or something else is returned like the word "done" or something like that, at which point is simply makes an alert or populated a div with a message... The point is, that depending on the number entered it could take up to an hour to complete ALL the queries, so I want the script that is called to only run a fixed amount of queries at a time and then return the number it is currently at (+1), so that it can continue with the next number when it is called again. I would like to use jquery, but could also be any other way, as long as I get this to work. I already have the php script completed that needs to be called by the ajax, it returns a single number when being called. Thank you, vb Hi guys I AM NEW TO PHP AND MYSQLI... TRYING TO CALL FUNCTION BUT I GOT ERROR CANT FIGURE OUT WITH IT IS, THANKS FOR HELP ME functions.php
<?php
echo mysqli_error($db);

THANKS
Hi All I am wanting to start writing neater coding so am wanting to refer to coding in a functions file. So for example, If i was getting info from database using the following code Code: [Select] $queryone = "SELECT * from affiliate where size='300x250' ORDER BY RAND() LIMIT 1"; $result = mysql_query($queryone); while ($row = mysql_fetch_assoc($result)) { echo "".$row['code'].""; } I would want this to go in a file called functions.php Then in my index.php(for example) I would want to link up to this code. Can anyone point me in the right direction please? Thanks! Please help me in this guys....... I am using MVC model for my application . I am stuck with the ajax call. this is my controller application/controller/admin/index.php function getCity() { $city=$this->model->getCity(); foreach($this->city as $key => $value) { echo '<option>'.$value['name'].'</option>' ; } } this is my model application/model/admin_model.php public function getCity() { if($_POST['id']) { $cid=$_POST['id']; $sth = $this->db->prepare('SELECT id, name FROM unit WHERE cid= :cid'); $sth->execute(array(':cid' => $cid)); return $sth->fetchAll(); } } this is my view <form id="city" action="<../application/admin/regstr/" method="post"> Country <select name="country" class="country"> <option value="" selected="selected">--Select Taluka--</option> <option value="1">India</option> <option value="2">USA</option> <option value="3">China</option> </select> City <select name="city" class="city"> <option selected="selected">--Select City--</option> </select> <input type="submit" /> </form> and this is my javascript for Ajax $(document).ready(function() { $(".country").change(function() { var id=$(this).val(); var dataString = 'id='+ id; $.ajax ({ type: "POST", url: "admin/getCity", data: dataString, cache: false, success: function(html) { $(".city").html(html); } }); }); }); But I am not getting the output. I have tested it with firebug in response tab. Instead of getting only option values html code as output I am getting the whole HTML page content (i.e. content of view page admin/index.php. Please help me out. I am currently building my own MVC Framework and I have run into an issue that I can't solve when attempting to use 2 methods from a single model. I know that this isn't an issue with the queries or information being return. I am unsure of the proper way that I can call 2 methods when checking to see if a user is logged in... The issue that I face is both methods are calling the DB and it throws a PDO error which I don't know how to get around the issue.. Any guidance would be nice as I have been banging my head over this issue. Thank you!

Edited July 14 by avargas94 Wrong Code Hi
I have an AJAX call that populates a select menu based on the selection from a previous menu. All works on on desktop browser, Safari, Firefox IE etc, however when using iOS the second select menu isn't populating.
the AJAX request is as follows
<script>
function getXMLHTTP() { //fuction to return the xml http object
var xmlhttp=false;
try{
xmlhttp=new XMLHttpRequest();
}
catch(e) {
try{
xmlhttp= new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e){
try{
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch(e1){
xmlhttp=false;
}
}
}
return xmlhttp;
}
function getTeam(strURL) {
var req = getXMLHTTP();
if (req) {
req.onreadystatechange = function() {
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200) {
document.getElementById('away-team').innerHTML=req.responseText;
} else {
alert("There was a problem while using XMLHTTP:\n" + req.statusText);
}
}
}
req.open("GET", strURL, true);
req.send(null);
}
}
function getGP(strURL) {
var req = getXMLHTTP();
if (req) {
req.onreadystatechange = function() {
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200) {
document.getElementById('gp').innerHTML=req.responseText;
} else {
alert("There was a problem while using XMLHTTP:\n" + req.statusText);
}
}
}
req.open("GET", strURL, true);
req.send(null);
}
}
</script>
and the trigger for it...
<select name="year" class="txtfield" onChange="getGP('find_gp_ajax.php?season='+this.value)">
Any ideas why the call won't work on iOS?
This is a bit of a more advanced question so I am hoping there are some advanced programmers online at this time . Anyways basically I want to be able to "queue" functions from a class in a single call and am wondering if I am doing it correctly or if there is a better way to do it. Here is my code: <?php class test { private static $one; private static $two; private static $three; public function callOne($val){ $one .= $val; return $this; } public function callTwo($val){ $two .= $val; return $this; } public function callThree($val){ $three .= $val; return $this; } public function print(){ echo $this->one.' '.$this->two.' '.$this->three; } } ?> now when I want to call this I can do: $test = new test(); $test->callOne('one')->callTwo('two')->callThree('three'); $test->callOne('another one'); $test->print(); Is there a better way to do this or is there a different method of doing this? Just wanna make sure I am doing it right lol. Hi there, I have already read some other topics concerning the same problem I am encountering. I have multiple applications which I programmed in PHP. In all of these applications I use a central authentication database and a central translation database (also on PHP). For this to work, I need to include a functions.php file for both the authentication db as for the translation db in all of my sites. Because I use different URL's for all my apps, including auth and transl, I am forced to use an URL when including both the functions.php files of the auth db and the transl db. As I found out (the hard way) PHP5 doesn't include the raw data of my functions.php files into the calling files, so none of my functions are known and I receive an error "Call to undefined function ...". Since I am using these programs only on an internal network (not public available), I am not afraid of any security issues. Is there any way I can include my functions.php files using an URL (like include ('http://trans.mysite.com/sys/functions.php');) so the defined functions in the functions.php file are known for the calling page? I hope I am not too confusing you all with my story, but I would really be very greatfull with some help. If needed I can also provide you with some more coding I used and configuring. I already checked my php.ini file and the following settings have already been applied: allow_url_fopen = On allow_url_include = On short_open_tag = On Many thanks in advance. This topic has been moved to Ajax Help. http://www.phpfreaks.com/forums/index.php?topic=334644.0 Can anyone figure out why this works in IE and Firefox but not Safari? Any help would be great.

I have written a script in php and need to use echo to see the values of variables etc. However I dont get the output on the screen while using echo . I am using Xampp server with Apache.

echo 'latitude- '.$lat . ', longitude- ' . $lon; Please help regards
Sanjish This topic has been moved to Ajax Help. http://www.phpfreaks.com/forums/index.php?topic=357605.0 I have a page that functions like this:
The user begins by loading ajaxtest.php, then using a drop-down menu, selects a user, after which a DIV on ajaxtest.php is populated with the user's selction to getuser.php?q=John%Doe
Here's a visual representation of what is currently happening, along with the part I don't understand.
getuser.php consists largely of a a large HTML table which interacts through PHP with my SQL database. Several of the fields in this table are editable, and after the user changes one of these fields, he can press an "update" button, which calls an AJAX script in update.js and runs update.php, which contains all my SQL queries to update the database, without the user being redirected to this update.php page. All of this is processing perfectly - the user makes some sort of edit, hits "update", and the database gets updated without any redirection or refresh.
Here's what I can't figure out though. Once the user makes a change, and hits "update," the database updates, but the end user doesn't see those changes that he made. I can't just do a simple page refresh, because the action is taking place on getuser.php, but getuser.php is loaded inside of a #DIV on ajaxtest.php. If I use something like window.location.reload(), this just refreshes ajaxtest.php and puts the user back to the starting point of having to select a user. This is not what I want. I don't want to refresh ajaxtest.php, I want to "refresh" ajaxtest.php with getuser.php?q=John%Doe insidethe DIV on ajaxtest.php.
It seems like this is very common - several forums have this capability, where a user has a page loaded, adds a comment, and sees that comment immediately without a full page refresh. I just don't know how to do it, and I've tried at lengths to search the web for an answer with no luck.
Can someone walk me through how to do this?
Where is my "Progr" return value?
This is not my first day using php but I don't code in the language that often. I don't understand why my dynamic variable is not returned in AJAX GET? Essentially, I need to give the client a simple UI so that they can copy files to a printer and I wanted to provide a little unfiltered feedback so they knew whether operation was a success. My feedback was just going to be output of exec() function though cleaned up slightly (perhaps replace line breaks with html break tags). PHP version is 5.2.17.17 and cannot be upgraded. Web Server Apache.
PHP dumbed down code:
exec("LoadZPL_PURL.bat", $output); Hello All, I have a PHP web application which will refresh itself(ajax calls connecting to the server and get the latest data) periodically. These also update the Database-based session handler class. i.e. There is NO UPDATE to the session data but the timestamp is constantly updated. Our problem is that garbage collection does not kick in as it looks at the difference between timestamp and session_gc.maxlifetime. So, if and the user is not interacting with the application. Now my question is how can I force the timeout even though refreshing happens but the user is not interacting with the application and there are "phantom" session updates made by these ajax calls. Please let me know. Thanks. Hello all I have a php and jquery/ajax call I am using to create a file/send an email. I get all the contents from my textboxes but I want a message to display on the screen afterwards being success or fail. In my .ajax call My call is exiting right before the ‘success:’ part. Why is my call not succeeding? Any tips/help will be appreciated Thank you

Since we are on linux we converted them to pem . In curl calls I could not find way to how to include both the root cert and the intermediate cert ,so I combined them by making a new pem file and copying the intermediate cert and them the root cert and naming it authority.pem . I am not sure whether it works or not and would like your opinion. 3.
